Shear forces, bending moments, and torsion [8].
How the structure transfers weight to its foundation [7]. Fundamental Structural Analysis
If you are looking to master these basics, consider these top-tier resources: Shear forces, bending moments, and torsion [8]
It is tempting to rely entirely on software like SAP2000 or Staad Pro [17]. however, professional engineers use fundamental formulas (like the simply supported beam point load equations ) to perform "sanity checks" on software outputs [2, 14]. If the computer says a beam won't bend but your hand calculation says it will, you've just prevented a potential site failure [10]. Essential Resources for Learning The amount of deflection or "sag" a structure
These structures can be solved using only the equations of equilibrium (e.g., simple beams and trusses) [7, 14].
The amount of deflection or "sag" a structure experiences under stress [8, 14]. The Three Sacred Principles
